Check domain is valid Node.js

Question

In Node.js, how can I check if a domain issued by the user is possible and contains allowed characters only?

I do not want to check if the actual domain is existent, only that it is syntactically correct.

Eg. something.something.something should be allowed, where "*)()-.net shouldn't.

I have tried to use some of the regexs on the question How to validate domain name in PHP? however, I'm actually unsure of how to use these in node. They seemed to always come out false.

Isn't this the sort of thing regex is used for? – Nov 03 '13 at 16:20 — , Nov 03 '13 at 16:20

The npm package validator would be the best choice and a trustable project:

var validator = require('validator');

validator.isURL('google.com', { require_valid_protocol: false }); //=> true

Package: validator

Try something like

var reg = new RegExp("[^a-z0-9-.]","i");
reg.test("asdasd.com")//returns false, invalid characters not found
reg.test("asd(.com")//returns true ,invalid characters found
